Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor
(2003)We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ... -
Evaluation of hand-held XRF for screening waste articles for exceedances of limit values for brominated flame retardants
(Environmental Protection Agency, 2019-03)Recent research has demonstrated the presence of restricted persistent organic pollutant (POP) brominated flame retardants (BFRs) in items such as children s toys and food contact articles. As the presence of these ... -
Evaluation of non-ideal piston stopping effects on the “adiabatic core” and ignition delay time simulation in rapid compression machines
(Elsevier, 2020-05-30)Piston creep and rebound are two non-ideal piston stopping behaviors in the rapid compression machine. Compared to nominal piston stopping, piston rebound/creep will result in a smaller/bigger 'adiabatic' core zone volume ... -
Evidence for long-term Gamma-ray and X-ray variability from the unidentified TeV source HESS J0632+057
(2009)HESS J0632+057 is one of only two unidentified very-high-energy gamma-ray sources which appear to be point-like within experimental resolution. It is possibly associated with the massive Be star MWC 148 and has been suggested ... -
Evolution and diversity of plant cell walls: from algae to flowering plants
(Annual Reviews, 2011-02-22)All photosynthetic multicellular Eukaryotes, including land plants and algae, have cells that are surrounded by a dynamic, complex, carbohydrate-rich cell wall. The cell wall exerts considerable biological and biomechanical ... -
Examination of oestrus-dependent alterations of bovine cervico-vaginal mucus glycosylation for potential as optimum fertilisation indicators
(Royal Society of Chemistry, 2021-03-09)Oestrus is the period in the sexual cycle of female mammals during which ovulation occurs, where they become most receptive to mating and are most fertile. Efficient detection of oestrus is a key component in successful ... -
Exceptional Vertex Operator Algebras and the Virasoro Algebra
(2008)We consider exceptional vertex operator algebras for which particular Casimir vectors constructed from the primary vectors of lowest conformal weight are Virasoro descendants of the vacuum. We discuss constraints on these ... -
Exceptionally bright TEV flares from the binary LS I+61 degrees 303
(IOP Publishing, 2016-01-20)The TeV binary system LS I +61 degrees 303 is known for its regular, non-thermal emission pattern that traces the orbital period of the compact object in its 26.5 day orbit around its B0 Ve star companion. The system ... -
Excess of rare novel loss-of-function variants in synaptic genes in schizophrenia and autism spectrum disorders
(Springer Nature, 2013-10-15)Schizophrenia (SZ) and autism spectrum disorders (ASDs) are complex neurodevelopmental disorders that may share an underlying pathology suggested by shared genetic risk variants. We sequenced the exonic regions of 215 genes ... -
An excitation emission fluorescence lifetime spectrometer using a frequency doubled supercontinuum laser source
(IOP Publishing, 2018-09-03)The accurate fluorescence analysis of complex, multi-fluorophore containing proteins requires the use of multi-dimensional measurement techniques. For the measurement of intrinsic fluorescence from tyrosine (Tyr) and ... -
Expansions of CAG·CTG repeats in immortalized human astrocytes.
(Oxford University Press, 2007)Expansions of trinucleotide repeats (TNRs) are the genetic cause for a number of neurodegenerative disorders. In some of these diseases, ongoing somatic expansions in the brain are thought to contribute to disease progression. ... -
An experimental and chemical kinetic modeling study of 1,3-butadiene combustion: Ignition delay time and laminar flame speed measurements
(Elsevier, 2018-09-10)Ignition delay times for 1,3-butadiene oxidation were measured in five different shock tubes and in a rapid compression machine (RCM) at thermodynamic conditions relevant to practical combustors. The ignition delay times ... -
Experimental and computational examination of anastellin (FnIII1c)-polymer interactions
(Wiley, 2016-10-24)Using a combination of experimental and computational approaches, the interaction between anastellin, a recombinant fragment of fibronectin, and representative biomaterial surfaces has been examined. Anastellin and ... -
An experimental and detailed kinetic modeling study of the pyrolysis and oxidation of allene and propyne over a wide range of conditions
(Elsevier, 2021-07-27)Allene and propyne are important intermediates in the pyrolysis and oxidation of higher hydrocarbon fuels, and they are also a major source of propargyl radical formation, which can recombine into different C 6 H 6 isomers ... -
Experimental and kinetic modeling study of 2-methyl-2-butene: allylic hydrocarbon kinetics
(American Chemical Society, 2015-03-20)Two experimental studies have been carried out on the oxidation of 2-methyl-2-butene, one measuring ignition delay times behind reflected shock waves in a stainless steel shock tube, and the other measuring fuel, intermediate, ... -
Experimental and kinetic modeling study of 3-Methyl-2-butenol (Prenol) oxidation
(American Chemical Society, 2021-08-19)Longer chain alcohols with 4–5 carbon atoms are attractive alternative fuels as they can be derived from biological sources and since their combustion leads to lower exhaust gas levels of NOx and soot compared to commercial ... -
An experimental and kinetic modeling study of cyclopentane and dimethyl ether blends
(Elsevier, 2020-11-13)Cyclopentane is a suitable naphthene, or cycloalkane, in a palette for multi-component gasoline surro- gate fuels due to its presence in market fuels and its relevance to alkyl substituted cyclopentanes also present. ... -
